My old priming system frequently floods. Is this normal?

Condensation buildup in the priming system’s vacuum tank is normal and typically varies seasonally. Regular draining keeps condensation buildup in check. LYNN offers automatic vacuum tank drains that can be furnished with our systems or easily added to existing systems.

Complete system flooding occurs with a failure of the priming valve seat or improper sizing of the priming valve. Properly designed priming systems provide complete protection of the vital system components in the event of flooding.
